I hope this helps you

10.4+3/4=40+3/4=43/4

-(7.4+1/4) = -( 28+1/4)= -(29/4)= -29/4

Find the general solution of the following equation. Express the solution explicitly as a function of the independent variable.

Mashcka [7]

Answer:

Therefore the general solution is

$2 \sqrt w = 2 ln(x) - 5 \frac1x +c$

Step-by-step explanation:

Integration Rule:

$\int x^n dx= \frac{x^{n+1}}{n+1}+c$
$\int \frac1x dx= ln(x) +c$

Given differential equation is

$x^2 \frac{dw}{dx}= \sqrt{w}(2x+5)$

$\Rightarrow x^2 dw= \sqrt{w} (2x+5) dx$ [ multiplying dx both sides]

$\Rightarrow \frac{dw}{\sqrt w}= \frac{(2x+5)}{x^2} dx$ [ dividing $x^2\sqrt w$ both sides]

Integrating both sides

$\int \frac{dw}{\sqrt w}=\int \frac{(2x+5)}{x^2} dx$

$\Rightarrow \int w^{-\frac12} dw=\int (\frac{2x}{x^2}+\frac{5}{x^2} )dx$

$\Rightarrow \int w^{-\frac12} dw=\int \frac{2}{x}dx +\int\frac{5}{x^2} dx$

$\Rightarrow \frac{w^{-\frac12+1}}{-\frac12+1} =2ln x+5 \frac{x^{-2+1}}{-2+1}+c$ [ c is arbitrary constant]

$\Rightarrow 2 \sqrt w = 2 ln(x) - 5 \frac1x +c$

Therefore the general solution is

$2 \sqrt w = 2 ln(x) - 5 \frac1x +c$

Ms.Ache is paid $1250 per week but is fined a $100 each day she is late to work.she wants to make at least $3,000 over the next

Fiesta28 [93]

There are 3 working weeks and each work week she earns $1250, so the total earning is:

total = 1250 * 3 = $3750

For each day of late, she is fined $100, and she must make at least $3,000. So she can only be late for 7 days so that her earning would be:

earning = 3750 – 7*100 = $3050

<span>Max number of days late = 7days</span>

Answer:

Yes , They would.

Step-by-step explanation:

value that "lies outside" (is much smaller or larger than) most of the other values in a set of data . Each if the numbers would be an outlier applying to the rule / function.
